A fuel cell car has been noted next generation automobile. Recent research focused on fuel cell which is the main part of fuel cell cars. Use of thinner stainless steel sheets in bi-polar plate can reduce the weight and volume of the fuel cell. There are various standards to get into the basic mechanical properties of material, but not in the case of thin sheet metal is not clarified. To get an exact mechanical property is important to evaluated formability of thin stainless steel sheets. In this study, we performed tensile test, erichsen test to evaluate the formability of thin stainless steel sheets.
It is difficult to mount a strain gauge on the thin sheet metal due to its weight. To improve the reliability of the tensile test, a CCD camera was used for calculation deformation.
Erichsen test is a cupping test to measure the ductility of a sheet metal and to determine its suitability for deep drawing. However, more than 0.1mm thickness material is used as the test apparatus. Erichsen spherical punch diameter of 8.0mm~20.0mm, that is not good for the sheet metal as thin as 0.075 to 0.15mm thickness, In the case of thin sheet metal small punch diameter is needed for experiment.
